Cable Reel

Abstract

A cable reel using a tape-shaped cable including a high-strength conductor having a tensile strength of 500 to 1500 N/mm2, an elongation percentage of 0.5 to 50% and a spring limitation value of 400 to 2000 N/mm2. Accordingly, in such a cable reel, weight as well as cost of the whole or parts in a cable reel can be reduced.

What is claimed is: 
     
       1. A cable reel comprising: a housing including an inner cylinder having an inner cylinder hole and an outer cylinder having an outer cylinder hole; and   a tape-shaped cable which is spirally housed in said housing, both end portions of said tape-shaped cable being introduced to outside of said housing through said inner cylinder hole and said outer cylinder hole, respectively;   wherein said tape-shaped cable includes at least one high-strength conductor having a tensile strength of from 500 to 1500 N/mm 2 , an elongation percentage of 0.5 to 50% and a spring limitation value of 400 to 2000 N/mm 2  ; and   wherein said cable reel absorbs relative rotation between an external member that generates an external force and said inner cylinder by tightening and loosening of windings of said tape-shaped cable.   
     
     
       2. A cable reel according to claim 1, wherein thickness of said conductor is from 0.01 to 0.1 mm. 
     
     
       3. A cable reel according to claim 1, wherein said tape-shaped cable includes a plurality of said conductors and insulated members for laminating to each other to hold said conductors therebetween. 
     
     
       4. A cable reel as claimed in claim 1, wherein said cable reel is adapted for use in an automobile. 
     
     
       5. A cable reel comprising: a housing including an inner cylinder having an inner cylinder hole and an outer cylinder having an outer cylinder hole; and   a tape-shaped cable which is spirally housed in said housing, both end portions of said tape-shaped cable being introduced to outside of said housing through said inner cylinder hole and said outer cylinder hole, respectively;   wherein said tape-shaped cable includes at least one high-strength conductor having a tensile strength of from 500 to 1500 N/mm 2  ; and   wherein said cable reel absorbs relative rotation between an external member that generates an external force and said inner cylinder by tightening and loosening of windings of said tape-shaped cable.   
     
     
       6. A cable reel according to claim 5, wherein said conductor includes an elongation percentage of 0.5 to 50%. 
     
     
       7. A cable reel according to claim 5, wherein said conductor includes a spring limitation value of from 400 to 2000 N/mm 2 . 
     
     
       8. A cable reel according to claim 5, wherein said tape-shaped cable includes a plurality of said conductors and insulated members laminated to one another to hold said conductors therebetween. 
     
     
       9. A cable reel according to claim 5, wherein said reel is adapted for use in an automobile. 
     
     
       10. A cable reel comprising: a housing including an inner cylinder having an inner cylinder hole and an outer cylinder having an outer cylinder hole; and   a tape-shaped cable which is spirally housed in said housing, both end portions of said tape-shaped cable being introduced to outside of said housing through said inner cylinder hole and said outer cylinder hole, respectively;   wherein said tape-shaped cable includes at least one high-strength conductor having an elongation percentage of 0.5 to 50%; and   wherein said cable reel absorbs relative rotation between an external member that generates an external force and said inner cylinder by tightening and loosening of windings of said tape-shaped cable.   
     
     
       11. A cable reel according to 10, wherein said conductor has a spring limitation value of from 400 to 2000 N/mm 2 . 
     
     
       12. A cable reel according to claim 10, wherein said tape-shaped cable includes a plurality of said conductors and insulated members laminated to one another to hold said conductors therebetween. 
     
     
       13. A cable reel according to claim 10, wherein said reel is adapted for use in an automobile. 
     
     
       14. A cable reel comprising: a housing including an inner cylinder having an inner cylinder hole and an outer cylinder having an outer cylinder hole; and   a tape-shaped cable which is spirally housed in said housing, both end portions of said tape-shaped cable being introduced to outside of said housing through said inner cylinder hole and said outer cylinder hole, respectively;   wherein said tape-shaped cable includes at least one high-strength conductor having a spring limitation value of from 400 to 2000 N/mm 2  ; and   wherein said cable reel absorbs relative rotation between an external member that generates an external force and said inner cylinder by tightening and loosening of windings of said tape-shaped cable.   
     
     
       15. A cable reel according to claim 14, wherein said tape-shaped cable includes a plurality of said conductors and insulated members laminated to one another to hold said conductors therebetween. 
     
     
       16. A cable reel according to claim 14, wherein said reel is adapted for use in an automobile.
